Hey there! :)

y = 3/4x - 2

To find the slope and y-intercept, simply use slope-intercept form to understand this.

Slope-intercept form is : y = mx + b ; where m = slope, b = y-intercept.

Therefore, you must ask yourself : which value is in the "m" spot and which value is in the "b" spot in our given equation?

Using this logic, we can come to the conclusion that :

Slope = 3/4 & Y-intercept = -2

Answer:the red box

Step-by-step explanation:

the red box since  1.26 is greater than 1.026, because the tenths place has the most power after a decimal. and the tenths place in the green box of sugar is 2, while the tenths place in the red box of sugar is 0 and 2 is greater than 0

hope this helps!

Answer:

Green box contains more sugar.

Step-by-step explanation:

Consider the provided information.

Ashley found 2 boxes of sugar in the kitchen.

The green box says 1.26 kg and the red box says 1.026 kg.

we need to find which box contains more sugar.

To find this we will first check the digit at ones place.

Both the digit has 1 at the ones place. So now check the digit at tenths place.

1.26 has 2 at tenths place while 1.026 has 0 at tenths place.

As we know 2 is greater than 0, thus the number 1.26 is greater than 1.026.

Hence, green box contains more sugar.

Answer:

The vertex form is y = -3(x + 2)² + 10

Step-by-step explanation:

* Lets revise how to put the quadratic in the vertex form

- The general form of the quadratic is y = ax² + bx + c, where

 a , b , c are constants

# a is the coefficient of x²

# b is the coefficient of x

# c is the numerical term or the y-intercept

- The vertex form of the quadratic is a(x - h)² + k, where a, h , k

 are constants

# a is the coefficient of x²

# h is the x-coordinate of the vertex point of the quadratic

# k is the y-coordinate of the vertex point of the quadratic

- We can find h from a and b ⇒ h = -b/a

- We find k by substitute the value of h instead of x in the general form

 of the quadratic

 k = ah² + bh + c

* Now lets solve the problem

∵ y = -3x² - 12x - 2

∵ y = ax² + bx + c

∴ a = -3 , b = -12

∵ h = -b/2a

∴ h = -(-12)/2(-3) = 12/-6 = -2

- Lets find k

∴ k = -3(-2)² - 12(-2) - 2 = -3(4) + 24 - 2 = -12 + 24 - 2 = 10

* Lets writ the vertex form

∵ y = a(x - h)² + k

∵ a = -3 , h = -2 , k = 10

∴ y = -3(x - -2)² + 10

∴ y = -3(x + 2)² + 10

* The vertex form is y = -3(x + 2)² + 10

ANSWER

The vertex form is:

[tex]y = - 3{(x + 2)}^{2} +10[/tex]

EXPLANATION

The given equation is:

[tex]y = - 3 {x}^{2} - 12x - 2[/tex]

[tex]y = - 3( {x}^{2} + 4x) - 2[/tex]

We add and subtract the square of half the coefficient of x.

[tex]y = - 3( {x}^{2} + 4x + {2}^{2} ) - - 3( {2})^{2} - 2[/tex]

We simplify to get,

[tex]y = - 3{(x + 2)}^{2} + 3(4)- 2[/tex]

[tex]y = - 3{(x + 2)}^{2} +10[/tex]

This is in the vertex form.

Answer:

Correct choice is A. [tex]y=x-8[/tex].

Answer:

Option b. 12

Step-by-step explanation:

This exercise asks us to find the derivative of a function using the definition of a derivative.

Our function is [tex]f(x) = x^{3}[/tex]. Therefore:

[tex]f(2+h) = (2+h)^{3}[/tex]

[tex]f(2) = (2)^{3} = 8[/tex]

Then:

[tex]\lim_{h \to \0} \frac{f(2+h)-f(2)}{h}=\lim_{h \to \0} \frac{(2+h)^{3}-8}{h}[/tex]

Expanding:

[tex]\lim_{h \to \0} \frac{(2+h)^{3}-8}{h} =\lim_{h \to \0} \frac{8+ h^{3} +6h(2+h) -8}{h} =\lim_{h \to \0} \frac{h^{3} +6h(2+h)}{h}[/tex]

[tex]\lim_{h \to \0} \frac{h^{3}+ 6h(2+h)}{h} =\lim_{h \to \0} h^{2} + 6(2+h) [/tex]

Now, if x=0:

[tex]\lim_{h \to \0} \frac{f(2+h)-f(2)}{h} = (0)^{2} +6(2+0) = 12[/tex]

Answer:

45/53

Step-by-step explanation:

SinR is opposite side's length divided by the hypotenuse. That means that the hypotenuse is 53 units, and the opposite side (the shorter-looking) is 28 units.

By the pythagorean theorem, that means the longer-looking one is √(53² - 28²) = 45 units long.

CosR is the adjacent side'd length divided by the hypotenuse. That means that is is 45/53.

The value of the cosR is 45/53 if the value of sinR= 28/53 after applying the Pythagoras theorem.

Trigonometry is a branch of mathematics that deals with the relationship between sides and angles of a right-angle triangle.

We have:

sinR = 28/53

Sin is the ratio of opposite to hypotenuse.

The length of the adjacent side from the Pythagoras theorem:

Adjacent side length = √(53²-28²) = 45 units

corR = 45/53

Because, cos is the ratio of adjacent to hypotenuse.

Thus, the value of the cosR is 45/53 if the value of sinR= 28/53 after applying the Pythagoras theorem.

Answer:

8.91 units.

Step-by-step explanation:

If the height = h then the radius = h/3.

The volume = 247 = π r^2 h

247 = π (h/3)^2 h

(h/3)^2 h = 247/π

h^3 / 9 = 247 /π

h^3 = 9*247/ π

h= 8.91 units.

The value of height of the cylinder is,

⇒ 13.14 units.

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

We know that;

The volume of the cylinder is,

⇒ V = πr²h,

Where V is the volume, r is the radius, and h is the height.

Given that;

The volume of the cylinder is 247 cubic units,

Also, we are told that the height of the cylinder is 3 times the radius of the base.

Hence, We get;

⇒ 247 = πr²h

And, Mathematically expressed, h = 3r.

Hence, Substituting value of h in the above equation,

247 = πr²(3r)

Simplifying further, we get:

247 = 3πr³

Dividing both sides by 3π,

r³ = 82.33

Taking the cube root of both sides,

r ≈ 4.38

Now, use the value of r and find the height of the cylinder, using the equation h = 3r.

Therefore, the height of the cylinder is:

h = 3 × r

h = 3 × 4.38

h ≈ 13.14

So, The value of height of the cylinder is 13.14 units.

The answer is:

The total height of the 17-story building is 74.29 meters.

This a unit convertion problem. We know that there is a 17-story building and the height of each story, we need to convert the units and then, calculate the total height.

We need to use the following convertion factors:

[tex]1meter=100cm[/tex]

[tex]1decimeter(dm)=10cm[/tex]

Now, converting the given units we have:

Meters to centimeters:

[tex]1meter=100cm[/tex]

[tex]4*1meter=4*100cm[/tex]

[tex]4m=400cm[/tex]

Decimeters to centimeters:

[tex]1decimeter(dm)=10cm[/tex]

[tex]2*1decimeter(dm)=2*10cm[/tex]

[tex]2dm=20cm[/tex]

So, we know that one story measures 4 meters, 2 decimeters (dm) and 17 centimeters (cm), and if we want to calculate the total height of the 17-story building, we need to use the following equation:

[tex]TotalHeight=17*(HeightDimension)[/tex]

[tex]TotalHeight=17*(400cm+20cm+17cm)=17*(437cm)=7429cm[/tex]

Now,

Converting from centimeters to meters, we have:

[tex]7429cm=7429cm*\frac{1m}{100cm}=74.29m[/tex]

Hence, we have that the total height of the 17-story building is 74.29 meters.

Have a nice day!

Answer:

h = 74.29 meters

Step-by-step explanation:

We know that a decimeter is equal to 10 cm.

and 100 cm equals 1 meter,

Then, each floor measures 4 meters + 2 decimetres + and 17 centimeters

This is:

4m + 20cm + 17cm

= 4m + 37cm

= 4m + 0.37 m

= 4.37 m.

If the building has 17 floors then its height is:

Final answer:

The recursive rule for the geometric sequence 1/2, -2, 8, -32 is defined by the first term a1 = 1/2, and for n > 1, the nth term is given by aₙ = aₙ₋₁ × (-4), illustrating the sequence's common ratio of -4.

Explanation:

The question asks for the recursive rule for a geometric sequence: 1/2, -2, 8, -32. To find the recursive rule, we need to determine the common ratio by dividing each term by its preceding term. For instance, dividing -2 by 1/2 gives -4, and similarly dividing 8 by -2 also gives -4. This shows that the common ratio (r) is -4. A geometric sequence can be defined recursively by specifying the first term and the rule for obtaining each term from the previous one.

The first term, represented as a1, is 1/2. Given that the common ratio is -4, the recursive rule for finding the nth term (an) can be expressed as aₙ = aₙ₋₁ ×  r, where n > 1. Substituting the common ratio, we get aₙ = aₙ₋₁ ×  (-4) for n > 1.

The correct symbol to fill in the blank is: c. > (greater than)

Therefore, HJ < HG is the relationship between the angles HJ and HG based on the given angle measures.

To determine the relationship between the angles HJ and HG based on the given information, which states that angle H equals 80° and angle J equals 45°, we can utilize the properties of angles in a triangle.

Considering the angles in a triangle, the sum of the interior angles equals 180°. Therefore, if we have the measures of angles H and J in triangle HJG, we can find the measure of angle HG.

Given:

Angle H = 80°

Angle J = 45°

Let's calculate angle HG:

In a triangle, the sum of all angles is 180°.

So, angle HG = 180° - (angle H + angle J)

= 180° - (80° + 45°)

= 180° - 125°

= 55°

Therefore, angle HG measures 55°.

Now, to determine the relationship between HJ and HG:

Angle HJ is opposite angle HG within triangle HJG, and since angle H is greater than angle J, which implies that angle HG is greater than angle HJ.

Hence, the correct symbol to fill in the blank is:

c. > (greater than)

Therefore, HJ < HG is the relationship between the angles HJ and HG based on the given angle measures.
